I just bought an 02 sierra with a 6.6 duramax, I want to pick up a tuner for it and i have already ordered an air intake. Does anyone have any ideas on which tuner is the bust for the duramax it seem everywhere i turn it's either dodge or ford stuff being sold, or is buying a tuner just a personal preferance and they are all pretty close to the same. Let me know your input it would greatly help, I just want the truck to be good all around driving.

I have the Bully Dog tripple dog programmer. I love it and have had no problems.

put an offer in on a power pup on ebay for it see what happens if i get it
